Capital punishment. Sends a chill down your spine, doesn't it? Hopefully none of our readers will ever see first-hand the following methods of execution in the following states of the US.

Buzzfeed put together a guide to the US' favorite forms of execution, with lethal injection being the most common way to say goodbye to crims. It's used in Mississippi, Alabama, New Hampshire, Connecticut, Texas, Pennsylvania, Missouri, Ohio, Illinois, Indiana, Maryland, Delaware, Viriginia, Kentucky, Arkansas, Tennesse, Louisiana, Alabama, Florida, Georgia, South Carolina, North Carolina, Oklahoma, Kansas, Nebraska, South Dakota, New Mexico, Colorado, Wyoming, Montana, Idaho, Arizona, Nevada, Oregon, Washington, and California.

First, the person is strapped down, and then different drugs are injected via an IV, each having their own nasty flavor: Sodium Thiopental to put you to sleep, Pancuronium to halt breathing, and lastly the killer Potassium Chloride, which stops the heart. Buzzfeed noted that interestingly, the states of Delaware, Illinois and Missouri go some way to protecting the people working over the execution, with the two employees each pressing a button at the same time. Only one of the buttons actually triggers the poisons, therefore only one technically killed the criminal—though which one, they'll never know.

Meanwhile, over in Alabama, Virginia, Florida, South Carolina, Kentucky, Tennesse, Oklahoma and Illinois (with the latter four states having certain restrictions and caveats), electrocution is the method prisoners are faced with.

Only a few more states remain in the US where the gas chamber is still legal—bad luck if you're in Missouri, California, Maryland, Arizona or Wyoming, though the latter three have restrictions based on when you were sentenced. Likewise, hanging is still legal in Washington and New Hampshire, and over in Oklahoma and Utah, death by firing squad is still possible. If injection or electrocution is found to be "unconstitutional," that is.
